Full Job Description

đź“‹ Description

  • • Design and execute fine-tuning strategies for structured generation and editing workflows using open-source language models such as Llama, Qwen, Mistral, and DeepSeek.
  • • Build supervised datasets from production-generated outputs, user edits, retries, and failures to improve model performance and output quality.
  • • Develop measurable benchmarks for generation quality, correctness, consistency, and runtime performance, moving beyond subjective review to data-driven evaluation.
  • • Implement LoRA, QLoRA, supervised fine-tuning (SFT), distillation, preference tuning, and synthetic data generation techniques to optimize model behavior for creative workflows.
  • • Construct automated pipelines for collecting, cleaning, evaluating, and promoting production interaction data into training datasets.
  • • Use validation systems, intermediate representations, runtime analysis, and rendered outputs as structured feedback signals to guide model improvements.
  • • Improve retry, repair, and self-correction workflows within AI generation pipelines to enhance reliability and user experience.
  • • Engineer natural-language-to-structured-content generation systems that preserve structural integrity and domain-specific constraints.
  • • Build structure-preserving editing and modification systems that enable precise AI-assisted changes to animated, graphical, or design-oriented content.
  • • Develop evaluation and observability pipelines to monitor generation quality, model drift, and system performance in real-world usage.
  • • Create smaller, lower-latency models tailored for targeted tasks such as generation, editing, routing, and repair in creative tooling environments.
  • • Design multi-step orchestration and self-correction workflows that enable AI systems to iteratively refine outputs based on feedback signals.
  • • Collaborate cross-functionally with engineering, design, and product teams to align AI system improvements with user needs and product goals.
  • • Debug complex systems spanning model outputs, validation logic, runtime behavior, and rendered results to identify root causes of failure or degradation.
  • • Define and implement objective evaluation criteria for structured outputs, ensuring consistency, correctness, and usability in production.
  • • Work with production usage and interaction traces to iteratively refine training data and model behavior for real-world creative workflows.
  • • Focus on production-grade AI infrastructure that prioritizes model reliability, scalability, and integration into user-facing creative tools.

🎯 Requirements

  • • Strong experience building with LLMs or structured generation systems in production or applied research settings
  • • Hands-on experience fine-tuning or adapting open-source language models
  • • Strong Python engineering skills
  • • Experience building evaluation systems, ML experimentation workflows, or data pipelines
  • • Strong understanding of prompt engineering, structured outputs, tool use, and model failure analysis
  • • Ability to define measurable evaluation criteria rather than relying only on subjective review

🏖️ Benefits

  • • Fully remote position
  • • Direct hire opportunity
  • • Work on real-world AI systems used in creative production workflows
  • • Collaborate with a highly technical and product-focused engineering team
  • • Tackle challenging problems involving structured generation, multimodal systems, and AI reliability
  • • Opportunity to shape production-grade AI systems for next-generation creative tooling
